I have one of the better qual ones. I wouldn't be comfortable loaning it out but If you want to bring the tank to me I'll drill it for you (no gaurentee, but I do have a drill press, diamond drilling lube and I've never cracked a tank in the drilling process)
If you want to take me up on that, I'm in Sudbury Ma and Sundays are best for me. Send PM if interested.
